Incomplete texts arriving
When I send texts from Message 7.0.1 (3314) from my 15" Retina Powerbook, some messages are delivered truncated on my wife's iPhone 4s (e.g. only first 27 of 29 words). However, the texts arrive complete on my iPhone 5. Both of us have up-to-date iOS 6 on our phones.
This happens more often with longer (more than one sentence) texts, but my texts are not overly long and the problem does not always occur.
If I copy/paste and resend the message from my iPhone, the text arrives complete on her iPhone.
I am not sending any photos with these texts.
Any idea how to fix this?
